The Romer-Lewin ring with inductors (part 4b) - Branch voltages and a spoiler

...and here I show how the rms voltages measured by the 'fast' voltmeter are the same as those shown by the scope.
I also insert a spoiler of the explanation of the apparently paradoxical result of seeing two completely different voltages 'across' the same two points: the voltages in the two branches of the circuit are indeed different (as we will see in a future video) but the voltmeters are not schizophrenic. As a matter of fact, when you have two voltmeters attached to the same two points on the opposite sides of the ring, each voltmeter is reading these two different voltages at the same time: the voltage of one branch with the correct value and - simultaneously - the voltage of the opposite branch altered by the linked EMF.
As strange as it might seem, this is NOT a probing issue. The voltages in the two branches are effectively different! It can be shown by looking at the total electric field inside the ring and by computing voltages as line integrals.
More on this in a future video on the theory behind this circuit .
Good news: it seems I have finally managed to install a working copy of OpenShot, so... no more fragmented videos!
